The invention provides a control method and system for the heating speed of a battery of a pure electric vehicle. The control method for the heating speed of the battery of the pure electric vehicle comprises the following steps that a current instruction of a d-axis is obtained; acquiring the output torque of the motor; determining the actual position of a rotor according to the obtained d-axis current instruction and the output torque of the motor; and determining a final current instruction of the d axis according to the current instruction of the d axis and the actual position of the rotor. According to the technical scheme, the actual position of the rotor is determined through the output torque of the motor, and then the compensation current for the d axis is obtained, so that the heating efficiency is improved.
